SAFETY-CATCH FOR BROOCH ES, ac.

$PECIFIGATION forming part of Letters Patent No. 719,919, dated February3, 1903.

Application filed June 20, 1901.

To all whom, it may concern.-

Be it known that I, GEORGE W.WASHBURN, of New York, in the county andState of New York, have invented a certain new and useful Improvement inSafety-Catches for Brooches and other Articles, of which the followingis a specification.

This invention relates to what are commonly termed safety-catches forthe pins of brooches, for safety-pins, and other kindred devices, theobject being to provide a catch whereby the pin, engaged therewith maybe locked within it, and thus the pins accidental disengagementtherefrom beprevented and the loss of the article be precluded.

In carrying out the invention 1 provide a tube closed at its outer endand open at its inner end and having an openingat one side by means ofwhich the pin may have its point inserted within the tube, wherein it islocked against accidental displacement by means of a surrounding slidingguard of peculiar construction applied to the tube frictionally in suchway as to hold it in adjusted position, all as I will proceed now morefully to describe and claim.

In the accompanying drawings, illustrating my invention, in the severalfiguresof which like parts are similarly designated, Figure 1 is aperspective view of a brooch with the pin free. Fig. 2 is a similar viewofabrooch with the pin locked. Fig. 3 is a side elevation, parts locked.Fig. 4 is an inner end elevation of the catch detached, with the guardpartly broken out. Fig. 5 is a cross-section of the tube takensubstantially in the plane of line A B of Fig. 6. r Fig. 6 is alongitudi nal section of the detached safety catch. Fig. 7 is an endview of the slide or guard detached. Figs. 4, 5, 6, and 7 are onsubstantially the same scale and enlarged with reference to Figs. 1, 2,and 3.

The plate or body 1, which supports the pin 2 and the catch 3, may be ofany approved construction and design. The catch itself comprises a hook4, having a foot 5 or other medium for connecting it with the plate orbody, and also having a bill 6. To this bill Serial No. 65,884. (tomodel.)

portion of the hook is applied a tube 7, the outer end 8 of whichpreferably is closed, while the inner end 9 next the hook is open, andin one side of this tube is a longitudinal slot or opening 10, which iscoterminous with the mouth of the bill of the hook.

It will be understood from the foregoing that the pin 2 is engaged withthe catch by slipping its point into the tube through the opening 10 andthe bill of the book. In order to lock thepin Within the tubewhen thusapplied and to provide for its retention therein against accidentaldisplacement, I employ a slide composed of a ring 11, within which is asplit ring 12, secured, as by solder, at 13 to the ring 11, and the saidsplit ring is a contractile ring in order to exert sufiicient frictionor pressure between the tube and the slide to hold the slide in anygiven position. As sufficiently indicated already, this slide is capableof movement longitudinally of the tube, so-that it may be moved to theouter end of the tube, as in Fig. 1, in order to uncover the slot in thetube sufficiently to permit the ingress and-egress of the pin and alsomay be moved inwardly, as in Figs. 2 and 3, to retain the pinwithin thetube. In order to prevent the escape of the slide outwardly from thetube, a stop 14 is provided at the outer end of the lateral opening 10in the tube and at substantially right angles to the tube.

It will be observed that the hook itself takes the strain that isimposed upon the pin in use, and thus the tube which is relieved of thestrain may be made quite light.

By the construction described a very simple and efficient safety-catchis provided for use in brooches, safety-pins of various kinds, and otherkindred articles.

I do not limit the invention to the exact details of construction; butan essential characteristic of my present device is a sliding guardsurrounding the pin-receiving tube and comprising a contractile splitring whereby the guard is securely held in its respective positions.

I use the term guard with reference to the device hereinbeforemechanically described as a slide, its function being that of a guard.

What I claim is 1. A safety-catch for brooches and the like comprising ahook, a tube having an end opening and a lateral opening, a pin whichenters said lateral opening when it is hooked, and a sliding guardhaving as part thereof a contractile split ring surrounding said tube.

2. A safety-catch for brooches and the like comprising a hook, a tubehaving an end opening and a lateral opening, a pin which enters saidlateral opening when it is hooked, and a sliding guard having as partthereof a contractile split ring surrounding said tube and a solid ringwithin which said split ring is secured.

3. A safety-catch comprising a pin-engaging hook, a tube having an openend adjoining the hook, a closed outer end, a pin-receiving lateralopening and a stop at the outer end of said lateral opening, and asliding guard having as part thereof a contractile split ringsurrounding said tube between said hook and said stop.

4:. A safety-catch, comprising a hook, a tube applied to the bill of thehook and-having an end opening and a lateral opening coterminous withthe mouth of the bill of the hook, and a guard consisting essentially ofa split ring next the tube and within an outer ring.

5. A safety-catch, for brooches and the like, comprising essentially ahook having a bill, a tube applied at substantially right angles to thesaid bill and having a lateral opening substantially coterminous withthe mouth of the bill, a stop at one end of said lateral opening, and aslide applied to said tube and comprising a contractile split ringembracing the tube and a surrounding solid ring to which the split ringis secured.
